The reason, the vast majority do a low mileage relates to the restrictions with a pcp.
Should a properly serviced motorbike, of any manufacturer, last for say 50K ?
One would hope so, however sometimes systemic faults do appear later on, which are often denied by the dealers; "never common across this or you're the only one" are phrases often used, although the internet helps refute this, and should really be fixed at the manufacturers cost.
Then there's the one off fault, where warranty should resolve the problem.
